Key Management for AI Agents

Key management for agents is how an agent’s signing keys are generated, stored, used and revoked. Because an agent’s key is what lets it prove identity and authority, a stolen key is a stolen agent. The disciplines are the familiar ones made sharper by autonomy: keys in a managed store rather than a file, scoped and short-lived where possible, and revocation that propagates fast — because an agent can act thousands of times before a human notices.

Managed secret store, never a file or repo
Revocation
Must propagate fast

Speed raises the stakes

A compromised human credential is dangerous; a compromised agent key is dangerous at machine speed. That is why scoping, short lifetimes and fast revocation matter more for agents, and why a key must never live in a file, a repository or an artifact — a committed key is burned the moment it lands and stays burned after the file is deleted.

Questions

Where should an agent’s keys live?

In a managed secret store or HSM, referenced by name — never in source, config or a build artifact, where history keeps them after deletion.

How is a compromised agent contained?

By revoking its key and the authority delegated to it, with revocation propagating faster than the agent can act — which is why attenuated, short-lived grants help.
